Detach result file operation does not work on PATRAN Ver.2007.01

When I tried to detach a result file, it did not work. Instead, I got the following error:
 
$# Detach external results file: D:\dd4_2_ori.odb
res_dra_detach_file( 1, 8, 24 )
$# Sql error : code = -999 vector = []; DbAbort in DbDeleteResCases. Occurred
$# in file db\results\resaccess\DbDeleteResCases.C at line 211
$# ==> A serious error occurred during database access in the prior operation.
$#    The prior operation is being undone.
$#    Any data created during that operation will be lost.
 
Does anyone encountered the same problem? What the solution? Thank you
  • These type of messages could occur if the attached file timestamps have changed or has been modified.
    Assuming you have not modified the file while it was attached, I would suggest that you delete all the result cases associated with the attached file. Then try to detach the file.
    See if you are able to detach the file without these messages.
     
    You also may want to try to use the later version of patran possibly 2017 and see if you are able to avoid this issue.
     
    Best Regards, I hope this helps.
